CHAIN BRAKE
WARNING: WE DO NOT REP- RESENT AND YOU SHOULD NOT AS- SUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. Kickback is a lightning fast ac- tion which throws the bar and rotating chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back toward the operator. Either of these events may cause you to lose control of the saw which could result in serious injury or even death. DO NOT RELY UPON ANY OF THE SAFETY DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK.
SThis saw is equipped with a chain brake. The brake is designed to stop the chain if kickback occurs.
S The
S If the brake is already activated, it is disengaged by pulling the front hand guard back toward the front handle as far as possible.
SWhen cutting with the saw, the chain brake must be disengaged.

CAUTION: The chain brake must be checked several times daily. The engine must be running when performing this proce- dure. This is the only instance when the saw should be placed on the ground with the en- gine running.
Place the saw on firm ground. Hold the han- dles with both hands and apply full throttle. Activate the chain brake by turning your left
wrist against the hand guard without releas- ing your grip around the front handle. The chain should stop immediately.
Inertia activating function control
WARNING: When performing the following procedure, the engine must be turned off.
Hold the chain saw approximately 14” (35 cm) above a stump or other wooden surface. Release your grip on the front handle and use the weight of the saw to let the top of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate.
IMPORTANT POINTS
SCheck chain tension before first use and after 1 minute of operation. See CHAIN
TENSION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics, masonry,
SStop the saw if the chain strikes a foreign object. Inspect the saw and repair parts as
necessary.
SKeep the chain out of dirt and sand. Even a small amount of dirt will quickly dull a chain and increase the possibility of kickback.
S Practice cutting a few small logs us- ing the following techniques to get the “feel” of using your saw before you begin a major sawing operation.
S Squeeze the throttle trigger and al- low the engine to reach full speed before cutting.
S Begin cutting with the saw frame against the log.
S Keep the engine at full speed the en- tire time you are cutting.
S Allow the chain to cut for you. Exert only light downward pressure.
S Release the throttle trigger as soon as the cut is completed, allowing the engine to idle. If you run the saw at full throttle without a cutting load, un- necessary wear can occur.
S To avoid losing control when cut is complete, do not put pressure on
saw at end of cut.
S Stop the engine before setting the saw down.
TREE FELLING TECHNIQUES
WARNING: Check for broken or dead branches which can fall while cutting causing serious injury. Do not cut near build- ings or electrical wires if you do not know the direction of tree fall, at night since you will not be able to see well, or during bad weather such as rain, snow, or strong winds, etc.
SCarefully plan your sawing operation in ad- vance.
SClear the work area. You need a clear area all around the tree so you can have secure footing.
